Broad protection against infectious bronchitis
Our client wanted to create an educational film about the mechanism of viral infection in infectious bronchitis for use in seminars for poultry producers. The film should focus on the fact that a specific vaccine only protects against a specific virus type and that virus strains with other surface proteins can still cause an infection. The message our client wanted to get across was that, depending on the targeted surface antigen, different vaccines can be grouped together into “protectotypes.” Moreover, combining vaccines with different protectotypes can generate an even broader immunization.
